Dry skin and dry .... down there?

I have a job that requires me to be in the sun for about 10 hours a day. So my skin gets really dry. I try drinking water and moisturizer but my skin is still flaking and cracking. But I’ve also noticed that my vagina is also shedding skin and seems dry. Does anyone else have this? It usually happens after I shave and I hate it. Does anyone have any tips to keep down there moisturized (I don’t want a yeast infection so I haven’t used any moisturizer)
